The block layer SG should have the identical behaviour as SCSI sg when
it comes to SG_SET_RESERVED_SIZE - allow caller to specify a large
amount, truncate to largest we support, and return that with
SG_GET_RESERVED_SIZE.  Currently we fail with -EINVAL if the value is
too large, I think the SCSI sg behaviour is more sane to use.  This
one-liner fixes it up, please apply for 2.6.8.

This fixes sparse warnings in fpa11_cpdt (coprocessor data transfer)
instruction emulation.  Note that pointers need to be cast to unsigned
long not unsigned int, so convert user registers to be unsigned long
type.

This cleans up and simplifies drivers, and also allows us future
simplification in the VFS layer, since it removes knowledge about
internal VFS layer handling of "f_pos".

Nobody ever fixed the big FIXME in sysctl - but we really need
to pass around the proper "loff_t *" to all the sysctl functions
if we want them to be well-behaved wrt the file pointer position.

This is all preparation for making direct f_pos accesses go
away.

 - conversion to seq_file, overflow fixes
 - qos_parse sanitized (3 sscanf calls instead of insane manual parsing)
	leaks plugged
	code cleaned up

We still have serious races, but they are general problem in atm code - it
has no locking whatsoever for any of the lists (mpcs, qos_head, per-client
lists).

Adds support for 'hh' (store number in char *) and 'll' (proper C99 for
long long) modifiers to sscanf().

no need for the mtrr code to check any more.

remove the run-time tests for it.

You can seek the tape, but you do it with the magic tape
control ioctl's, not with lseek/pread/pwrite.

unnecessary tests at read/write time.

Remove the test from the socket code, now that it's no
longer necessary.

file descriptors.

This also removes the ESPIPE logic from pipes and seq_files,
since the VFS layer now supports it. 

Adds a cleaned up version of the PPC4xx DMA engine library.  Converted to
new DCR access method and DMA API.

Due to speculative execution, a CPU may execute some instructions after the
rfid.  This makes profiles confusing, since profiling ticks could end up in
those instructions following the rfid that are never executed.

- Remove unused includes.
- Be consistent about printing irq numbers, avoid a mix of decimal and

- Remove prototypes from xics.c, they should be in xics.h.
- Remove infinite loop on failure, and instead use panic. Panic has a chance to
  log the error message on the LED panel and reboot the box, a while(1) loop
  does not.
- xics isnt compiled for iseries any more, so no need for the

This patch just cleans up arch/ppc64/kernel/pci_dn.c a bit, including:
	- remove it from the iSeries build completely
	- small changes to Makefile
	- remove the "post" parameter from traverse_pci_devices as
	  noone used it
	- make traverse_all_pci_devices static
	- remove CONFIG_PPC_PSERIES tests as we no longer build for iSeries
	- some reformatting (closer to "standard")
	- remove some of pointer casts

This has been built (with default config) on pSeries and pmac and built and
run on iSeries.
